6010D (0.001 Ω to 100 kΩ)
Features and Benefits
The AccuBridge® 6010D Resistance Bridge (furthermore 6010D) is the metrologist’s choice for primary lab level resistance measurements. Recognized as the world’s leading Automated Resistance/Thermometry Bridge, the 6010D is ideal for resistance measurements in both resistance metrology and temperature thermometer applications. With its innovative technology, the 6010D’s speed, measurement accuracy, and data handling capabilities, make it the preferred primary resistance measurement system in National Measurement Institutes (NMIs) and other primary labs worldwide. The 6010D is designed for flexibility and ease of use.
Ratio Range and Accuracy
The AccuBridge® Direct Current Comparator (DCC) with its binary wound current comparator technology balances current with effective resolution of 25-bit. It provides ratio measurements with an accuracy to better than 40 ppb. It covers a ratio range of from 14:1, with a linearity of better than 5 ppb. The 6010D can perform ratio measurements with resistances valued from 0.001 Ω to 100 kΩ. A line of optional high current range extenders permits measurements down to 1 μΩ for shunt resistance measurement applications.
Automated Resistance Operation
The AccuBridge® Direct Current Comparator (DCC) with its binary wound current comparator technology balances current with effective resolution of 25-bit. It provides ratio measurements with an accuracy to better than 30 ppb. It covers a ratio range of from 14:1, with a linearity of better than 5 ppb. The 6010D can perform ratio measurements with resistances valued from 0.001 Ω to 100 kΩ. A line of optional high current range extenders permits measurements down to 1 μΩ for shunt resistance measurement applications.
Automated Temperature Operation
The 6010D Bridge itself can ratio a standard resistor to another resistor being tested. Optional 10-, 16- or 20-channel scanners can be used individually or together to connect to up to 80 channels of ratio measurement for up to 40 different test resistors to be calibrated.
The 6010D is perfectly suited for front panel operation or you can team it with MI’s 6010 SW Windows®-based operating software for fully automated measurements, history logging, graphing, and regression analysis. Standalone operation with the touch sensitive display panel provides full bridge capabilities to the operator. Ratio or direct resistance measurements can be made. Multiple measurements over time can be numerically displayed or graphically displayed to best fit your needs.
Automated Temperature Operation
Measurements International’s Accu-T-Cal™ SW is a software package for the automation of measurements and calibration of platinum resistance thermometers using the 6010D as the measurement device. Accu-T-Cal™ SW is based on over 15 years of experience and research of metrologists from Laboratory of Metrology and Quality, Faculty of Electrical Engineering, University of Ljubljana (UL-FE/LMK). All measured data is available as graphical and tabular format and is automatically saved for detailed analysis and calibration report generation.
The AccuBridge® Family of Bridges
The 6010D is a high performance model MI Bridge. One of a family of bridges where there are various bridges optimized for different tasks, from measuring Quantum Hall Resistance (QHR) standards over a smaller range of resistance but with excellent uncertainties, to others which are a better fit for other labs with broader range of measurements but with larger uncertainties. There are three different bridge designs which use different measurement methods to measure over 21 orders of magnitude of resistance, from 1 μΩ to 10 PΩ. The AccuBridge® family offers the best line of bridges available for measuring the widest range of resistance.
The 6010D measures both ratio and absolute values. You select functions using the menu on the large touch screen display. For absolute measurements, you enter the value and related uncertainty of the standard resistor using the display’s keypad. You enter the measurement functions such as current through the unknown resistor, settle time, number of measurements, and number of statistics the same way.
You can verify the calibration accuracy by performing an interchange measurement at any ratio. The interchange technique works at all ratios from 14:1.
The 6010D’s low-noise, touch screen display is interactive with the measurements, as shown in the screen images below. When a reading is complete, the average value and uncertainty (based on the number for statistics) are displayed. All uncertainty calculations are 2 sigma level.
